T0 all whom it may concern;

Be it known that I, JACKSON 'FRAzEE,;.a citizen-of the United States, residing .in the city and ,county of San Francisco, State .of California, have invented certain new-and useful Improvements Supports .forIPunch ing-Ba s,;.and I-do herebydeclare the following to e a full, clear, andexactdescription of;thesame.

The invention isdesigned .for the suspending of an ordinary punching-bag from the ceiling, rafters, or other overhead support, the objectofthe invention being toeliminate or reduce to a minimum the friction caused between the movable parts from which the bag. issus ended, whileat the same time overcoming t e binding of the parts during the swinging movement of the. ba and provid- .for the free .movement of t e suspension cord or rope when the punching-bag is swung upward its full distance, which rope, with the supports generally employed, has .a tendency. to bite into the lower edge ofthesupport "as the gpunching-ba :is swung upward, and thus prevents the fullupward movement and uniform swin of the said punching-bag.

To comprehen the invention, reference should be had to the raccompanylingsheet of drawings, wherein G Figure 1 is a view of the support secured to an overhead beam or ceiling, disclosing the suspension-cord attached at one end to the support and a section of a punching-bag connected to the lower end of the said cord. Fig. 2 is a detail vertical sectional view of the support, a section of the suspension-rope being illustrated secured within the rope-holding block of the support; and Fig. 3 is a plan view of the base-plate of the support.

The numeral 1 indicates a'circular baseplate, which plate is designed to be secured to the ceiling or overhead support by any suitable meansas, for instance, by screws 3. This base-plate isformed with a dependin extension 45, within which is rotatably held the stem 5, said stem passing through a central openin' in the depending extension 4 of the base-p ate, being held in osition by means of a nut 7, which nut ho ds onto the stem5 a cone 8. This cone 8 bears onto a series of balls 9, arranged within a circular seat 10, formed within the socket or bore 1 1 of the extension 4, which extension and the baseplate 1 may be formed integral. a

The outer end portion 12 of the stem 5 is slightly enlarged and formed with a coneshaped shoulder 13, which sh'oulder when the stem is properlypositioned, Fig. 2 of-the drawings, bears onto a lower series of balls 14, arranged within aperipheral seat .15;in'the outer edge or lowerend ofthe extensionp l.

By this means there is provided a double ball-bearing surfacefor the rotatable stem 5, which reduces friction between'therotatable stem 5 and the extension 4to a minimum, the stem being thus free to rotate with the least retardation of movement.

Onto the outer enlarged screw-threaded end 12 of the stem 5 is screwed the shell or thimble 16, which is formed with the dependin claws 16, said claws holdin the sphere or ba 117, which sphere orball is ee to turn or move within the cup-shaped seat 18 formedby the outer end of the enlarged portion '12 ofthe stem 5 and the securing-claws 16 'Thelength of the claws '16, of which, preferably, three are used,'is such as to embrace the sphere 1.7 for the greater portion of its circumference, thereby preventing the sphere falling from its position, althoughthe same is free to rotate or'turn freelyin alldirections within its .sea't'18. A universal joint'isthus formed 'between'the sphere 17 "and the "holder or thimble 16, which holder or thimbleby reason of its engagingportion shall hereinafter be referred to as a sphere-holder.

The sphere or ball 17 has dependin therefrom a short extension 19, to whic is attached the rope-holder 19. This holder is formed with a socket 20, which is intercepted by a side openin 20. Through this side opening is inserted the upper end of the suspension-rope21, which rope is securedtherein by means of the small ball 22. This ball is inserted within the socket 2O rior to passing the suspension-r0 e throug the opening 20, so that when the older 19 is turned into a downward position, Fi 2 of the drawings,

and a slight pull exerte on the suspensionrope the ball 22 will move downward and bite into the rope, thereby jamming, so to speak, and binding the said rope into the holder 19 To the lower end of the suspension-rope is secured the punching-bag 23.

By means ofthedescribed support free movement is obtained in all directions, inasmuch as the stem rotates with little or no friction within the depending extension of the base-plate, and the sphere or ball, to which the sus ension-cord holder is secured, being held to 1ts holder. by a universal-joint connection the same is permitted universal move- ITO ment to conform to the swinging movement the extension of the base-plate and projecting therefrom, of bearing-balls within the said extension a ainst which the rotatable stem works, a holder secured to the projecting end of the rotatable stem, a spherical member held Within said holder so as to have universal movement therein, and a securing member for the suspension-rope carried by the spherical member. I

2. A sup ort for punching-bags comprising a suitable ase-plate, a stem rotatably connected thereto, a holding-shell secured to the lower end of said stem, a spherical member loosely held within the shell of the said stem so as to have universal movement therein, and a suspension-rope holder secured to and depending from the spherical member, and balleari'ngs interposed between the stem and the base-plate.

3. A support for punching-bags comprising a suitable base-plate, a stem rotatably connected thereto, a spherical member united to the said stem by a universal-joint connection, a suspension-rope holder secured to the s herical member, a socket in said holder for t e insertion of one end of the suspensionrope, said socket being intercepted by a side opening in the holder and through which the end of the suspension-cord extends, and a movableball 0r lock device fitted Within the socket of the rope-holder.

4. A su port for unching-bags comprising a suita le base-p ate, of a stem rotatably connected thereto, a spherical member held thereto by a shell depending from the rotatable stem, and a rope-holder secured to and depending from the spherical member.

5. A support for punching-bags comprising a suitable base-plate, of a stem rotatably held therein, ball-bearing between the stem and an extension of the base-plate, a spherical member connected to the stem by means of a shell carried by the stem, and means carried by the spherical member for uniting thereto one end of a suspension-rope.

6. A support for punching-bags comprising a suitable base-plate, an extension depending therefrom, circular seats formed therein, a series of balls arranged in each seat, a stem rotatably held within the said depending extension, cone-surfaces on the rotatable stem which bear onto the series of balls, a holder for a spherical member secured on the lower end of the rotatable stem, a spherical member held Within said holder so as to have universal movement, and means carried by said member for the attachment of a suspension-rope thereto.

In testimony whereof I have hereunto affixed my signature in the presence of Witnesses.
